Many terrorists associated with the Islamic State still exist. Some will continue to fight and terrorize. Plus there are Muslims who have used the Islamic State as an excuse for terror.

The Islamic State wants war (jihad). Here is something from the Islamic State’s publication Dabiq:

Jihād in this era is an obligation upon each and every Muslim as numerous lands of the Muslims have been usurped by the kuffār and numerous parties of apostasy have arisen therein. Until all these lands are retaken, cleansed of apostates, and ruled by the Sharī’ah, the obligation does not drop. … Allah said, {And prepare against them whatever you are able of power and of steeds of war by which you may terrify the enemy of Allah and your enemy and others besides them whom you do not know [but] whom Allah knows} [Al-Anfāl: 60].(The Murtadd Brotherhood. Dabiq, issue 14, Islamic year 1437–October 2016, p. 36)

‘Jihad’ supposedly means ‘holy war.’

The Bible shows that terrorism is prophesied:

14 ‘But if you do not obey Me, and do not observe all these commandments, 15 and if you despise My statutes, or if your soul abhors My judgments, so that you do not perform all My commandments, but break My covenant, 16 I also will do this to you: I will even appoint terror over you, wasting disease and fever which shall consume the eyes and cause sorrow of heart. And you shall sow your seed in vain, for your enemies shall eat it. 17 I will set My face against you, and you shall be defeated by your enemies. Those who hate you shall reign over you, and you shall flee when no one pursues you. (Leviticus 26:14-17)

25 The sword shall destroy outside; There shall be terror within (Deuteronomy 32:25)

12 “Cry and wail, son of man; For it will be against My people, Against all the princes of Israel. Terrors including the sword will be against My people; Therefore strike your thigh. (Ezekiel 21:12)

12 Behold, these are the ungodly,Who are always at ease; They increase in riches…19 Oh, how they are brought to desolation, as in a moment! They are utterly consumed with terrors. (Psalms 73:12,19)

25 Because you disdained all my counsel, And would have none of my rebuke, 26 I also will laugh at your calamity; I will mock when your terror comes, 27 When your terror comes like a storm, And your destruction comes like a whirlwind, When distress and anguish come upon you. (Proverbs 1:25-27)

5 Also they are afraid of height, And of terrors in the way (Ecclesiastes 12:5).

The prophecy about “terror within” is pointing to terror within the borders of places like the USA, UK, and Canada.

The Syrian-Iraq based Islamic State has provided terror to many places.

The Bible specifically warns about acts from Palestinians and Syrians to affect the British-descended peoples:

8 The Lord sent a word against Jacob, And it has fallen on Israel. 9 All the people will know — Ephraim and the inhabitant of Samaria — … 11 Therefore the Lord shall set up The adversaries of Rezin against him, And spur his enemies on, 12 The Syrians before and the Philistines behind; And they shall devour Israel with an open mouth. (Isaiah 9:8-9, 11-12)
